General Description
The MAX260/261/262 CMOS dual second-order universal
switched-capacitor active filters allow microproéessor
control of precise filter functions. No external com-
ponents are required for a variety of bandpass, low-
pass, highpass, notch and allpass configurations. Each
device contains two second-order filter sections which
place center frequency, Q, and filter operating mode
under programmed control.
An input clock, along with a 6-bit to program input,
determine the tilter's center or corner frequenca
without affecting other filter parameters. The filter
is also programmed independently. Separate clock
inputs for each filter section operate with either a
crystal, RC network, or external clock generator.
The MAX260 has superior offset and DC specifications
than the MAX261 and MAX262 and a center frequency
(to) range ot 7.5kHz. The MAX261 handles center
frequencies to 57kHz while the MAX262 extends the
center frequency ran e to 140kHz by employing lower
clock-to-fo ratios. Al devices are available in 24-pin
DIP and small outline packages in commercial, ex-
tended, and military temperature ranges.
